In Figure 1, the outer and inner surfaces of Pivotedto one sideof this passage 26 is a bar .15 a wall are rep-resented by 1 and 2 respectively. 28 adaptedto turn on the pivot 29. This bar Attached to the face of surface 1 is 'a-plate 3 extends past the surfaces and 2 and its outer and hinged to this plateas at 4 is a cover 5 end is reduced to form a projection 30 (see of the contour shown and which again meets Figs. land 8) which fits 111a cut 31 of the actuthe plate 3 in a locking device at G which ator 17. ()nthe same end of thebar 2S and adjacent to the projection is a trip 32 pivoted at 33 and which is under the action of the spring 34 acting between the trip and the bar 28. On the actuator 17 is a block 35 located so as to engage with a shoulder 36 on the trip 32 and extending from the cover 5 is a pin 37 which acts as a throw off for the trip. The inner end of the bar 28 carries apunch holder 38 held in place by the set screw 39 and the punch 40 is retained in the holder by the screw 41, the whole forming perforating or visible recording means. The punch holder 38 has downwardly projecting portions 42 over which is the compression spring 43 acting against the holder 38 and the lip 44 of the plate 45. This plate 45 is placed upon and fixed to the plate 27 (Fig. 4) and in addition to the lip 44, it'has an upward extension 46 which serves as a guide for the bar 28 (Fig.

and also on this same plate 45 is an outwardy extending portion 47 having an edge 48 to form cutting means and an opening 49 through which the punch 40 passes in the punching operation. Above plate 45 and similarly fixed to plate 27 is plate 50, a portion of which is bent as shown at 51 and this bent portion has an aperture 52 for a use to appear hereafter. In Fig. 5, the cover 5 is shown in part and in which there is a slot 53 through which the actuator 17 extends and there is also in this cover 5 an aperture 55 which registers with the platen 12 (Fig. 1). To block this aperture 55 when the device is in normal position, I provide a shutter or closure 56 which is faced to and moves with the actuator as shown in Fig. 1 so that normally this shutter prevents access to the platen 12 and no such access is possible unless and until the shutter 56 is taken from in front of the aperture 55 by movement of the actuator 17, such action being shown in Fig. 2. Furthermore, I provide signal means, both audible and visual, as follows. \Vithin the cover 5 andv attached to the plate 3 are two spring eonductingstrips 57 and 58 separated by the insulation 59 and 60 and having terminals such as at 61 and 62 from which lead the wires 63 and 64. On the upper end of the conducting strip 57 is a cam or roller 65 and a contact point 66 while the upper end of strip 58 has a contact point 67. The contact points 66 and 67 are normally separated while the roller 65 is preferably in continuous contact with the cam surface 68 of the actuator 17. The wires 63 and 64 lead to a sounding device such as a bell or a buzzer and a source of power as is well understood in the art. The visual signal means are illustrated by a lamp 69 fed by the wires 7 0 and 71 and so arranged that it projects into the hood 72 (Fig. 5) formed in the cover 5 and which has an aperture 73 to throw the light downward upon the aperture 55. The wires and 71 are in the same circuit with the wires 63 and 64 so that whenever the circiut of (33 and 64 is closed by the contact points 66 and 67 to give the audible signal, the circuit of 70 and 71 is similarly affected to light the lamp or visual signal.

In Figure 8 I show a modification of the perforating or recording means as follows. Instead of the bar 28 and its related parts, I modify the plate 45 somewhat shown and place the punch 40 in the core of a solenoid as at74; this solenoid having a cover 75 and the core is normally held upwards by a spring 76 acting between the core and the cover. Loosely mounted upon a pivot 7 7 is a trip 77 held against the pin 78 by the spring 79 but which is free to move upward away from this pin. Arranged to coact with the trip 77 and pivoted at 80 is a contact piece 81 having a cam face 82 and a contact point 83 and adjacent to contact point 84 held in the piece 85. The wires 86 and 87 and the solenoid leads 88 and 89 serve to energize the solenoid whenever the contact 83-84 is closed and these wires may either lead to a separate source of power or may be incorporated in either or both of the signal circuits, it being understood that all of these circuits may 'be varied to suit conditions and that the source of power is not important except that it be adequate to the needs of the device.

In the operation of my device, the normal inoperative position is shown in Fig. 1 where the record tape 7 passes from the rear of the storage roll, forward and over the platen 12 (which may be called the registration platen), under the platen 14 (which may be called the feed platen) and thus through the closed passage 26 until it emerges through the opening between plates 47 and 51 and under the punch 40 on the interior end of the device as shown in Figs. 1 and 2. Operation occurs by movement of the actuator 17 from its normal position of Fig. 1 to any intermediate point between that and the position of Fig. \Vhen the actuator is so moved, it carries with it the shutter 56 to expose the record tape 7 on the endorsing platen 12 through the aperture 55.

Also the cam surface 68 of the actuator 1.7 flexes the strip 57 to make contact between the points 66 and 67 to close the signal circuits whereupon the buzzer or hell will sound and the lamp 69 will light both as a signal and to illuminate the endorsing surface in the aperture 55. Both of these signals will continue in action as long as the actuator is held away from its normal position. Also as the actuator is moved, the block 35 goes upward, engages the shoulder 36 of the trip 32 and raises the bar 28 which in turn forces the perforating means downward at the interior end of the device so that the punch 40 passes through the record tape 7 and makes the permanent and visible record that the call register has been operated and a call made. By the time the perforation has been made, the trip 82 has been raised to a point where it contacts with the pin 37 whereupon the trip is moved out of engagement with the block 35. hen this occurs, the spring 43 which has been compressed in the perforating opera tion, then restores the perforating means up wardly, and as thatrip 32 is out of engagement the bar 28 resumes its normal position by turning about the pivot 29. Also in this movement of the actuator 17, the pawl 18 is pulled over the ratchet 2O this ratchetbeing held against movement by the stop 2O so that. the platen 12 does not move nor does the record tape 7; in other words, thefeeding means just mentloned 1s prepared for subse quent action. Therefore, from the foregoing it will be seen that a movement of the actuator away from normal exposes varying degrees of the record tape on the registration platen in accordance with the extent of such movement, that the perforating means is actuated to make the visible and permanent rec- 0rd and is restored, that either or both of the audible and visual signal means are operated and that the feedingmeans is prepared also to act in proportion tothe extent of actuator movement. When the actuator 17 has been moved as just described, and as illustrated in Fig. 2, its spring 23 isextended and when the actuator is released, this spring causes the return movement to normal in such movement and the feeding means having beenprepared, the pawl 18 causes the ratchet 20 and the platen. 12 to rotate and thus'feed' the record tape 7 forward under the feed platen 14, through the closed passage 26 and out over the cutting edge 48 on the interior end of the device. At the same time, the shutter 56 is moving with the actuator 17 to close the aperture and the roller is moving from the high part of the actuator cam surface 68 to break the contact 66 67 and open the circuit of the audible and visual signal means; the bell or, buzzer and the lamp 69.

Consequently, as the actuator resumes its nor.

projection 30 of the bar 28 is entered in the recess 31 of the actuator 17 (see also Fig. 8) and this recess is. directly above the shaft 11. This provides a locking means so that if an attempt be made to operate the perforating means in any way other than by the actuator, the bar 28 cannot move because of projection 30 being held in recess 31 and there fore the perforating means remain immov- I able unless legitimately operated.

The modification of Fig. 8 is shown with the parts in normal position; this modification referring only to the perforating means so that the other parts of the device remain the same. As the actuator 17 moves away from normal, the trip77 is carried upward by the pin 78 and rides over the cam-surface 82 of the piece 81 which rocks this piece about its pivot and makes contact between the points 83 and 84 to close the circuit including wires 86 -87 and 8889. This energizes the solenoid 74 to cause the punch 40 to pass through the record tape 7. The action is only momentary for as the trip 77 passes the cam face 82, the piece 81 recovers to normal position under the action of the spring 81 and breaks the contact between the points 84 and 88 so'that the solenoid becomes inactive and the punch 40 is with drawn upwards bythespring 7 6. As the actuator 17 moves backward to its normal position in a counter-clockwise direction, the

trip 77 rid-esdown over the cam surface 82 of the piece 81 against the tension of the spring 79 until thetwo are clear whereupon the spring 79 returns the trip 77 to its position against the pin 78.

From the foregoing-disclosure of my invention, many advantages will be found among which'may be mentioned that every operation of the handle gives an unalterable visible reco'rdof the call which, together with whatever message is endorsed uponthe record tape, immediately passes beyond the control of the operator and is concealed from him so that it cannot againbe reached. The extent of movement of the actuator determines the surface of tape exposed up to the full opening of the aperture in the cover so that messages of varying length may be written and also one of indefinite length bysuccessive movement of the handle, each portion of themessage so made passing out of sight of the operator. 'Therefore not only does each movement of the actuator perforate the tape and cause the signals to work as long as this actuator is away from its normal position but every message is'held from the view andcontrol of every one but the proper person. As a check upon calls and messages and to prevent tampering :from the interior, the record tape may be out by the edge 48 to form a zero line and ones initials or other mark may be placed on the inner end of the tape through the aperture 52 so thateverything subsequentto that point can be determined with certainty as it appears on thetape with assurance that no part of the tape with its record has been removed. The continual action of the signals while the handle is, held away from normal insures the operator being heard and even'without a written message on the tape, the perforation registersthecall and a succession of such perforations may signify the absence of "any employee left in charge. These perforations record the number of calls and their proximity to each other gives an indication of the action of the actuator a series of closely spaced perforations indicating probable partial operation by the same person while regularly spaced ones, a series of separate calls. Tampering with the perforating means is excluded because of the locking arrangements spoken of and by the cover over the solenoid in the case of electrical perforating.
